This invention relates to a window ventilation mechanism, and moreparticularly to a side window ventilation mechanism for use in motorvehicles. The invention is principally directed to ventilation which iseasily controlled, effective and provides freedom from draft for thevehicles occupants. A characteristic feature of the invention consistsin providing a pane directed forwardly and outwardly and another panedirected forwardly and inwardly which may be shorter, serving as adiverting pane so that said panes or wings will form a V-shaped airscoop or air deflector having a V-shaped lateral section, the sectionplane extending in the driving direction. Both panes suitably revolveabout separate axes substantially vertical to the driving direction, sothat they may be eventually turned from a closed position to an openone.

The improvement provided by the present invention consists in that thewind caught by the pane opening obliquely to the outside and serving toventilate the inside of the vehicle, is turned forwardly by the otherpane, the turning pane opening obliquely to the inside, thus obviatingevery kind of draft in the vehicles interior,

though affording efiicient ventilation. At the same time the occupantsare protected against rain and dust, the window of the inner ordiverting pane not obstructing the vision or bein available as a blindwindow dimming the light, if developed accordingly, e. g. in colours.Moreover this window ventilation mechanism is simple and can be operatedin a simple way.

A further characteristic feature of one embodiment of the presentinvention consists in that said panes, either of which is turnable tothe outside and the other to the inside, are disposed in such a way thatopening the one pane will simultaneously open the other in the oppositedirection. In a most simple way this result is eventually obtained bydisposing the revolving axes of the two panes so as to be displaced inthe driving direction,'whereby, for example, the pane opening outwardlyextends beyond its turning axis and theprolonged portionof said pane,serving at the same time for tightening, will have contact with theother pane and open it likewise. These revolving panes suitably form thefront part of a motor car side window, so as to avert, when opened in a\'-shape, the wind in a forward direction towards the windscreen ortowards the bottom space lying underneath. Similar mechanisms howevermay be provided also on the rear side windows of the vehicle or even onits roof, in which latter case therevolving axes eventually providedwill extend substantially in a horizontal plane. Further features of thepresent invention relate to the linkage of the windows, to fixing thepanes in the chosen position and to tightening the windows against theWindow frame.

A preferred embodiment of this invention is represented in theaccompanying drawings and described in detail, though the invention doesnot remain within the scope of this embodiment. The term: a revolvingaxis substantially ver tical is intended to include a revolving axisdeviating more or less from the vertical position, provided only theresult desired by the invention is obtained.

In the drawings:

Figs. 1 and 2 represent in a horizontal longitudinal section the frontpart of a motor vehicle body having a window ventilation mechanismaccording to the invention,

Fig. 1 showing th revolving panes in the closed position, and

Fig. 2 showing them in the opened position,

Fig. '3 is a side view of the window ventilation mechanism asrepresented in Fig. 2, while Fig. 4 is a horizontal section through thelinkage portion of the invention, showing th outer pane closed and theinner pane turned in the opposite direction by degrees.

Fig. 5 represents the same embodiment with the two panes being opened,and

Fig. 6 is a side view of the hinge part of the pane revolving inwardly.

The frame posts i and 2 of the front pane or windshield 3 of theautomotive vehicle constitute or form part of a frame firmly connectedwith the walls of the automotive vehicle, each being 4 and 5respectively. The doors 4 and 5, respectively, are strengthened byframes 6 and I, respectively, on the rear frame ledge of which the sidewindows 8 and 9, respectively, can be raised or lowered. On their frontedge, both windows 8 and 9 are guided through interposed frame bordersl0 and I I within the window frame E5 of both doors 6 and 5.

In accordance with the present invention, there is shown in the Figures4, 5 and 6 the above mentioned intermediate frame border ill for theslidable window 9, 2| the pane turnable outwardly and 22 the paneturnable inwardly. The former is supported in a hinge axis 23, thelatter in a hinge axis 24, the two hinge axes being displaced withrelation to the driving direction, so that the hinge axis 23 operatingthe outer pane is somewhat distant from the frame border E0. The pane 2!in this case is prolonged rearwardly beyond the turning axis 23 andprovided, towards the frame border ID, with a U-shaped rail 25, servingas a receptacle for a rubber tightening border 26 abutting in the closedposition on the frame border ID.

The inner pane 22, as indicated by arrows, can be turned by 180 degreesso that in the one position indicated in Figure 4 in full lines saidpane is facing the slidable window in parallelism, while in the otherposition marked with dotted lines it extends adjacent and in parallelismwith the outer pane 2!. The inner pane 22 may be hinged to the windowframe by means of a bottom pivot 21 resting in a supporting bearing 28disposed on the window frame. On its top end, said inner pane issupported by an angle iron 28 secured to the window frame and a screw3%. Between the bottom pivot bearing 28 and the abutting surface 3! ofthe pane there is inter posed a circular spring 32 fitted in such a wayas to generate friction pressure between the pivot bearing 28 and thepane in the direction of the hinge axis 24. By suitably adjusting or bychanging the circular springs any desired friction may be obtained.sufiicient to fix. the pane 22 in any desired position whatever.

If the inner pane 22 is in the position indicated in Fig. 4 by fulllines, and the outer pane 21 is turned outwardly, the position of thepane 22 remains unaltered. If however the latter is in the position 22.,indicated by dotted lines, turning the pane 2| outwardly will cam therearward prolonged portion of. the last named pane, by means of therubberized border 26, with the inner pane 22 and pushes it inwardly asrepresented in Figure 5, the two panes 2i and 22 then forming a V-shapedair-scoop opening for wardly.

For the purpose of ventilating the interior of the vehicle body, one orboth outer turnable panes 2| may be turned outwardly and simultaneouslythe corresponding inner panes 22 are turned inwardly, so that the twopanes, as revealed by a horizontal section represented in Figures 2 and5, will form a V-shaped air scoop or air deflector opening forwardly.

By these means the wind streaming along the side wall of thevehicle-body and caught by the outer pane will fiow towards thediverting surface and directed inwardly of the inner pane, thusdeviating, as indicated in Figure 2 by arrows, forwardly towards thefront Windshields ES and towards the bottom space extending underneath.This current of air will result in an efiicient ventilation of thevehicles'interior and more particularly in an efficient cooling of, thebottom space grown warm, while the space extending behind the turnablewindows remains completely free of draft, the occupants at the same timeremaining unmolested either by dust or by rain.

The diverting panes or inner panes 22 are suitably also made of glass orof any other transparent material. They may also be colored and/or ofsuch dimensions as to serve in addition as sun protectors.

If the two turnable panes are supported by a common axis, a similarresult. might be eventually obtained by interposing a reversing gearbetween the pivots of the outer and the inner pane so that turning theone pane outwardly will automatically turn the other pane inwardly.There may be eventually provided a. coupling de vice to permitdisengaging the two panes.
